Phys.org / Black hole 'blast' reaches 300,000 light-years

A team of researchers has discovered that winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery ...

Phys.org / A step closer to artificial organs: UV light shapes arteriole-scale hydrogel vessels

The creation of fully artificial organs is a sci-fi dream, and researchers in Japan may have brought it one step closer to reality by developing a new photofabrication technique (i.e., a light-controlled synthetic method) ...

Phys.org / Gobi fossil reveals 6-inch 'Cretaceous rabbit' belonged to a different mammal branch

A remarkably preserved fossil from Mongolia's Gobi Desert is reshaping scientists' understanding of mammal evolution during the age of dinosaurs.

Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought

Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...

Medical Xpress / Beyond arthritis: Three causes of hip pain that can lead to joint replacement

When an adult sees a doctor and complains about persistent hip pain, the assumption is often wear-and-tear-related osteoarthritis. However, hip pain not caused by arthritis can come from conditions that are both more complex ...

Phys.org / In biology of cells, octopus has another trick up its sleeve

The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core ...

Phys.org / One LED produces four stable colors at room temperature

Full-color displays normally require separate red, green and blue light emitters. A team from the University of Osaka and Ritsumeikan University has demonstrated another approach: a single light-emitting layer that produces ...

Phys.org / One of industry's toughest lignin byproducts could become feedstock for valuable chemicals

The pulp and paper industry, which manufactures everything from tissue paper to cardboard, also generates a significant yet often overlooked byproduct—a complex polymer called lignin. Around 100 million tons of lignin are ...

Phys.org / Hydrothermal microbes shape seafloor minerals at newly found vents near Greek island

In August 2023, the German research vessel METEOR set sail on Expedition M192 to the Greek island of Milos with Dr. Solveig Bühring as chief scientist. The mission was to locate and investigate previously unknown hydrothermal ...

Phys.org / Tabby's star may be orbited by a planetary-mass companion

By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...

Phys.org / Strain turns non-chiral crystals left- or right-handed on demand

Mechanical strain is one of the most common tools used to tailor the properties of materials. In piezoelectric materials, stretching or compressing a crystal generates an electrical polarization. In piezomagnetic materials, ...

Medical Xpress / Chemicals present in drinking water may carry a hidden risk tied to uterine cancer

In a recent study, researchers examined whether certain chemicals present in public drinking water are linked to uterine cancer, the most common gynecological cancer in the United States and one that has been steadily increasing ...
